Introduction

Going back to what we learnt about measurement scales and the distributions, this is generally how you could match the different types of variables with the different types of description:

Categorical variables

  • Frequency table
  • Bar chart
  • Pie chart
  • Mode

Continuous variables

  • Histogram
  • Mean (if normal distribution)
  • Median (if skewed distribution)
  • Minimum
  • Maximum
  • Variance
  • Standard deviation
